Simple chaetae is lacking in <i>P. proceraeae</i> as far as is known, but presence of simple chaetae in anterior chaetigers can not be excluded as these chaetae are broken.</p>Published as part of <i>Nygren, Arne, 2004, Revision of Autolytinae (Syllidae: Polychaeta)., pp. 1-314 in Zootaxa 680</i> on pages 102-103, DOI: <a href="http://zenodo.org/record/157809">10.5281/zenodo.157809</a>

Autolytus roseus Claparede 1864
No full textAutolytus roseus Claparède, 1864 Autolytus roseus Claparède, 1864: 566 –567, pl. 7, fig. 4; Langerhans 1879: 577; Fauvel 1923: 322, fig. 123 E–G. Not Autolytus roseus Okada 1933 a: 641 –645, fig. 1 (= Epigamia sp) Distribution. Mediterranean. Remarks. Types do not exist. Female stolon, length 10 mm for? 8 + 13 + 40 chaetigers. Tentacular cirri 2 pairs, achaetous knobs not described. Antennae and dorsal cirri red, tentacular cirri uncoloured, red intrasegmental (Claparède 1864: fig. 4) band across each segment; eggs blue. General body shape with a long posterior region, indicates that this is a stolon of Proceraea type. It is possible that this is the female stolon of Langerhans' P. madeirensis. The colour in P. madeirensis is described as brown, but red and brown may sometimes be difficult to separate. In that case Claparède's name would have priority.Published as part of Nygren, Arne, 2004, Revision of Autolytinae (Syllidae: Polychaeta)., pp. 1-314 in Zootaxa 680 on page 192, DOI: 10.5281/zenodo.15780
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
